Radio panels here could be paper-based Bakelite, or hard rubber (Ebonite). Structural parts might be linen-based Bakelite which is tan or black and generally shows the weave of the cloth through the surface. We were still using the linen-based phenolic in the machine shop where I worked, and I brought home offcuts up to an inch thickness, and some tubing.
